Description

Technical Field

[0001] The utility model relates to the technical field of injection molded shoes, in particular to an environment-friendly injection molded shoe. Background Technique

[0002] An injection molded shoe is a kind of shoe product made by injection molding process. It injects plastic materials such as PVC, TPR or PU into a mold after heating through an injection molding machine, and forms a shoe sole under certain temperature and pressure. An injection molded shoe refers to the shoes produced by an injection molding machine. Narrowly speaking, it refers to the cloth shoes worn by students produced by an injection molding machine. It is popularly produced in the coastal areas of Zhejiang in China, with cheap prices and novel styles.

[0003] For example, the authorized announcement number "CN203279902U" is a kind of injection molded shoe. By blocking the joint between the shoe upper and the side of the shoe sole, it changes the traditional bonding method of the shoe sole and the shoe upper, making the appearance of the shoe more beautiful and the bonding more firm. However, for existing injection molded shoes, since an integrally injection molded shoe sole is used to paste the upper shoe body above, a qualified injection molded shoe can be produced in this way. However, when an injection molded shoe is worn on a person's foot, when the wearer walks, the shoe mainly relies on the heel and the sole of the injection molded shoe to bear the force. When the wearer squats and runs, the front sole position of the injection molded shoe will be affected by the bending between the sole and the toes and generate an arc. Therefore, after wearing an injection molded shoe for a period of time, the sole is prone to cracking and breaking. Because it is not easy to bond and fix the injection molded shoe sole after molding, once the sole of the injection molded shoe breaks and opens, it is difficult to repair and can only be discarded. Therefore, the discarded injection molded shoes will affect the environment and cause a large amount of shoe waste, seriously affecting the environmental protection of the use of injection molded shoes. Content of the Utility Model

[0024] The support plate 81 can be made of a thick rubber layer with strong toughness embedded inside the outsole 5. A plurality of vertical connecting columns 82 are fixed inside the support plate 81. The connecting columns 82 suspend and support the lower fixing blocks 84 on the front and rear sides inside the outsole 5. The front and rear rows of fixing blocks 84 are connected by anti-cracking ribs 83. The anti-cracking ribs 83 are made of multiple horizontal high-strength rubber strips. The anti-cracking ribs 83 can provide an inward pulling force on both sides of the sole when the outsole 5 is worn and bent, so that the outsole is not easily broken. In this way, the sole will not be frequently broken and discarded, and the environment-friendly injection-molded shoe can be used more environmentally friendly.

[0025] The injection-molded shoe buffering structure 6 includes a shoe upper sole 61 and a connecting layer 65. The shoe upper sole 61 is fixedly connected above the insole 1 of the shoe. A plurality of vertical blocks 62 are fixedly connected below the shoe upper sole 61. A plurality of damping balls 64 are fixedly connected to the lower ends of the plurality of vertical blocks 62.

[0027] Working principle:

[0028] Using an environmentally friendly injection-molded shoe can strengthen the toughness and crack resistance of the sole of the injection-molded shoe. In this way, when wearing and using the injection-molded shoe in daily life, the sole can be more durable and does not need to be replaced and discarded frequently, thus achieving a more environmentally friendly purpose.

[0029] The sole anti-cracking structure of the environmentally friendly injection-molded shoe:

[0030] By using a support plate 81 with relatively strong toughness and embedding a thick rubber layer inside the outsole 5 of the shoe. A plurality of vertical connecting columns 82 are fixed inside the support plate 81. The connecting columns 82 suspend and support the lower fixing blocks 84 on the front and rear sides inside the outsole 5 of the shoe. The front and rear rows of fixing blocks 84 are connected by anti-cracking ribs 83. The anti-cracking ribs 83 are made of a plurality of horizontal high-strength rubber strips. The anti-cracking ribs 83 can provide an inward pulling force on both sides of the sole when the outsole 5 of the shoe is worn and bent, so that the outsole of the shoe is not easily broken or damaged. In this way, the sole does not need to be discarded and replaced frequently due to frequent breakage.

[0031] The ground elastic buffering structure of the environmentally friendly injection-molded shoe:

The shoe upper sole 61 is used to be fixedly pasted on the upper of the lower shoe insole 1. When the wearer puts on the injection-molded shoes, the sole of the foot will step on the upper of the shoe upper sole 61, and then the multiple vertically arranged blocks 62 will push the damping balls 64 to press on the lower docking blocks 63. In this way, the elastic deformation of the damping blocks 64 can make the sole of the wearer's foot more elastic and improve the comfort. The lower ends of the multiple docking blocks 63 are fixedly connected with a connecting layer 65. The lower part of the connecting layer 65 is connected to the support plate 81 and the heel 3 by means of pasting and fixing.
